Conservation of Energy

In physics, the rule of the conservation of energy states that energy doesn’t disappear from the atmosphere; instead, it changes its form from one type to another. Energy is one of the most important physical quantities in nature, and it cannot be created or destroyed — only transformed.

The acceleration of a particle is given by a = -ks?, where a is in meters per second squared, k is a constant, and s is in meters. Determine the velocity of the particle as a function of its position s. Evaluate your expression for s = 11 m if k = 0.3 m²'s² and the initial conditions at time t = 0 are so = 7 m and v = 41 m/s. -2 %3D Answer: v = m/s
